Product Description

Bend Insensitive Single-mode Fiber

Our bend-insensitive single-mode fiber has the characteristics of small geometric size and bending insensitivity, which can maintain good optical properties under the condition of small bending radius, and can meet the requirements of small-size optical cables and optical devices. it is widely used in optic fiber hydrophone and other industries. The optic fiber can be specially designed according to the needs of users to meet the requirements of mode field diameter, cutoff wavelength and bending sensitivity. This series of optic fiber preform adopts in-tube chemical vapor deposition process, which has the advantages of low hydroxyl group, high numerical aperture and good optical uniformity. The double-layer UV-curable acrylic resin coating of optic fiber is specially designed for optical devices with small bending radius, reducing bending additional attenuation, showing excellent optical properties, high tensile strength, long-term fatigue resistance and so on.
